Abstract

Collision control system ( 40 ) for controlling deflection of an instrument cluster ( 30 ) in a vehicle during collision. Said collision control system ( 40 ) comprises a steering assembly ( 10 ) including a steering wheel ( 12 ) and a steering column ( 11 ), a cross car beam ( 20 ) comprising a first sliding surface ( 22 ), and an instrument panel assembly ( 35 ) including an instrument cluster ( 30 ) and a second sliding surface ( 32 ), which is arranged to abut and slide along said first sliding surface ( 22 ) during said collision. During collision said steering column ( 11 ) is configured to move forward in a controlled manner and said steering column assembly ( 10 ) is arranged to push said instrument cluster ( 30 ), such that said second sliding surface ( 32 ) of said instrument panel assembly ( 35 ) slides along the first surface ( 22 ) for controlled deflection of the instrument cluster ( 30 ).
